IMPROVEMENT IN PORTABLE SKIDS.

Specification forming part of Letters Patent N 0. 169,990, dated November 16, 1875; application filed October 16, 1875.

reference marked thereon, which form a part of this specification.

My invention relates to improvements in portable skids, for the purpose of loading and unloading articles of merchandise to and from wagons, wharves, warehouses, 850.; and consists, in combination with the ordinary frame and its braces, of a number of rolls freely movable around their centers in hearings in the frame, which rolls project a little above the upper side of the frame, but do not project as low asthe lower part of the frame, by which I am able to load and unload boxes and similar articles of merchandise with great ease, and with very little friction, by drawing them up or down on that side of the skid having the rollers projecting above the frame. By reversing the skid Ican use it for the purpose of loading and unloading barrels, or similar convex articles, in the usual manner, without interfering with the rollers.

In one end of each of-the frame-timbers is placed a T-shaped bolt, for the purpose of attaching the skid temporarily to the rail of the wagon, 860., to or from which the goods are to be moved. The object ofsaid T-shaped bolts is tosecure the skid in position with either side upward, for the purpose of moving flat and convex articles of merchandise.

On the accompanying drawings, Figure 1 represents a perspective view of my improved skid, and Fig. 2 represents a cross-section over one of the rollers.

Similar letters refer to similar parts wher- 1 ever they occur on the different parts of the drawings.

a a represent the frame-work, and b b the braces, in the usual manner. a c 0 represent the rollers, movable in bearings in the frames at a, and having a portion of their convex surfaces projecting above the upper side of the frames at a, so that boxes, bars, 8270., can be moved up and down on the rollers without touching the frames a a, thereby relieving a great deal of the friction that would exist if the goods were moved directly on the frames to a, as is the common occurrence on the ordinary skids. The rollers 0 00 are placed so near the upper side of the frames 01. a that the skid can be reversed for the purpose of moving barrels or similar convex goods by rolling them directly on the frames at a without coming in contact with the rollers c c. c, as repre sented in dotted lines in Fig. 2. The frames to a are provided in one end with T-shaped bolts 01 d, for the purpose of securing the skid to the rail of a wagon, 860., with either side upward.

I am aware of the patent granted on the 2d day of July, 1867, No. 66,426, to Francis Van Doren, in which a rollerskid is shown having a solid flat bottom, and I therefore dis- In testimony that I claim the foregoing as R my own invention 1 have affixed my signature in presence of two witnesses.
